TO ALL rWHOM IT MAY CONCRN:

Be it known that I, WILLIAM J. HASWELL, of Waverly, in the county of Tioga, `and State of New York, have invented a new and Improved Spring Bottom for Beds, Seats, die.; and I do hereby declare that the followthe same,`reference being had to the accompanying drawings, forming part of this specification, in-.which- Figure 1 represents a longitudinalivertical section of this invention. i Figure 2is a plan or top view of the same.

Similar letters of reference indicate like parts.A .i p This invention relates to a bedstead or other frame the side and end'piees of which are slotted and` provided with a series of rollers. Over these rollers are drawn a series of straps which connect at their upper ends with i a piece of canvas or sther suitable flexible material, and at their lower ends with springs retained by rods, which extend along the lower edges of the side and end pieces of` the bedstead, being retained by suitable buttonsd` By these means a bottom for beds, chairs, sofas, &c., is obtained, the tensionsof which can be easily regulated and which is free to accommodate itself to the form of the body. p A represents a bedstead, the side and end pieces of which are perforated with slots or mortises, a, as shown;

in the drawing. To the top edges of these slots are secured a series o'f rollers, b, over which `pass straps, c, and

these straps are connected at their upper ends ,to the bed bottom, B,'and at their lower ends to` springs, d. The

bed bottom, B, is formed of a piece of canvas or any other suitable flexible material andthe springs are retained by rods, e, which extend along the bottom edges of the side and end pieces of. the bedstead,`and are retained by buttons, f. By turning these buttons the rods can be removed and the springs can be easily withdrawn. Thev` i i straps, c, are provided with buckles, g, so that they can be lengthened or shortened and the tension of the bed bottom can be regulated. The bed bottom, being iiexible and` supported by a series of springs is free to i accomodate itself to the form of the body of the person 'occupying'the bed, and a cheap, durable, and convenient f bed is obtained. It is obvious that this `improvement is `applicable to chairs, sofas, lounges,`carseats, and other i l articles of the same nature. p

What I claim as new, and desire to secure by Letters Patent, is- The springs d, passing down through mortises in the sides and ends of the bedstead `or frame A, in combii nation with movable rods e, straps c, and the` flexible bottom B, all constructed and operating substantially in t the manner and for the purpose set forth.
